Goodman 20201901 Condensate Drain Hose Tube

The Goodman 20201901 is a genuine OEM condensate drain hose tube engineered for the GMH950453BXAF 96% AFUE gas furnace and compatible Goodman/Amana high-efficiency models. This flexible drain tube routes acidic condensate away from the secondary heat exchanger and collector box to the drain trap, keeping your furnace running dry and code-compliant. A cracked, brittle, or clogged drain hose is one of the most common causes of pressure-switch lockouts, water pooling, and nuisance shutdowns during the heating season.

Specifications

Part number: 20201901
Part type: Condensate drain hose tube
Equipment: Gas furnace (condensing / 90%+ AFUE)
Material: Flexible corrosion-resistant tubing
Fitment: Direct OEM replacement for GMH950453BXAF

OEM vs. Generic

This is a true OEM Goodman part, molded to the exact length and inner diameter the furnace was designed around. Generic aftermarket tubing often has the wrong bore or wall thickness, leading to kinks, poor drainage, and repeat failures. Choosing OEM ensures a leak-free seal at the collector box and drain trap the first time.

Install Difficulty

Easy — DIY friendly (1 of 5). Most homeowners can swap this hose in 10–15 minutes with basic pliers. Power down the furnace, disconnect the old hose from the barbed fittings, drain any standing water, and press the new tube on. Verify no kinks and confirm free drainage before restoring power.
